Create a simulated Broadlink device for E2E tests #75
Description
Is your feature request related to a problem? Please describe.
End to end tests start the host application with a NullCommandService for Broadlink commands, which means none of the Broadlink support is being tested.
Describe the solution you'd like
Create a simulated Broadlink device, similar to the SimulatedTiVoDevice, which the application can connect to in test scenarios.
Additional context
Follow the specifications and implementation plan in _spec_SimulatedBroadlinkDevice.md (added in PR #74)
